If the same data has been modified differently in both the publisher and the subscriber databases, synchronization will result in a conflict which has to be resolved - either manually or by using pre-defined policies. rowguid needs to be configured on a column if merge replication is configured. Merge replication Changes made at both the publisher and subscriber databases are tracked, and periodically the changes are synchronized bi-directionally between the publisher and the subscribers. Transactional replication synchronizes databases in near real time.

SQL Server supports three different types of replication: Transaction replication Each transaction made to the publisher database (master database) is synced out to subscribers, who update their databases with the transaction. Replication follows a publisher/subscriber model, i.e., the changes are sent out by one database server ("publisher") and are received by others ("subscribers"). SQL Server Replication Services are used by SQL Server to replicate and synchronize database objects, either in entirety or a subset of the objects present, across replication agents, which might be other database servers across the network, or database caches on the client side. The Service Broker, which runs as a part of the database engine, provides a reliable messaging and message queuingplatform for SQL Server applications. For cross instance applications, Service Broker communicates over TCP/IP and allows the different components to be synchronized together, via exchange of messages. Used inside an instance, it is used to provide an asynchronous programming environment.
